Abstract (en)

[origin: WO02073773A1] The invention relates to a winding structure for an electrical machine comprising a multiphase winding wherein a plurality of coils or groups of coils (50, 52; 54, 56) connected in parallel are connected to a continuous conductor rail (40, 42, 44, 46). The coil ends are thereby linked with the electrical power feed directly and without any intermediate elements. Preferably, the conductor rails (40, 42, 44, 46) are disposed on one or on both faces of the stator of the electrical machine outside the groove, in the area of the stator back. The invention further relates to a corresponding method for producing a winding structure of a multiphase winding wherein a plurality of coils or groups of coils (50, 52; 54, 56) of the winding are connected in parallel and are connected to a continuous conductor rail (40, 42, 44, 46).
